An Upper Bucks County woman accused of shooting and killing her husband had apparently been putting angry postings on the internet for some time, accusing her husband of fathering a child with another woman. Pennsylvania State Police say 49-year-old Dorleen Burklund allegedly shot her 47-year-old husband Michael about eight times in the back late Sunday afternoon following one of many arguments at their home on Mink Road in the Kintnersville Section of Springfield Township. She is being held without bail at the county prison on a first degree murder charge, and Bucks County District Attorney David Heckler says investigators will look closely at her mental health history.
